To all whom it may concern;

Be it known that I, EUGENE W. Yocnp, a citizen of the United Sta es, residing at -of Illinois, have invented certain new and i A useful Improvements in Ant-icreepers for '1 Rails, of which'the following is a specificin tioii.

,2: movement of railroad rails, and more par- ,;ticularly'to'improveinents n devices known .as anti-creepers, or rail anchors. It is wellknown that the passage of trains .15 over railway tracks tends to, shift the rails I flongitudi'n-ally'in the direction of the move- -vment'ofthetrains When the trains run in' yopposite' directions on the same tracks the I double trackroads, the creeping or shifting e as to be danof the rails is so consider-a 5 gerous unless prevented,

Anti-creepers areprimaiily for use on i doubletrack rttilroads, 'in wl ich their principal'fifunctioii is to prevent creeping in one l direction only. Ithowev'er frequently hap- 80,-pen's' that there iss'uflicient traffic even on the normal traffic to produce a creeping in a reversedirection to that resisted by the anti- Ifltends'to'dis'engage the anti-creepers from rgtheir lockedrelationf between the rails and vvadjacentjtidso that when traffic is-resumed win the-normal directionthe anti-creepers are 4 0,.,-ine'ifectiveto prevent creeping. It is there i t fo're desirable that an anti-creeper should be 'sb.,.c'onsti"ucted, and have'such an engagement with the rail", that it will prevent creeping "n-the norinalfdireetion after the rail has rept infill directionreverse to that of the normahor iafter contraction of the rail has Specification of Letters Patent.

pro'vide'a rail anchor the effectiveness, of

which to prevent creeping of a rail in one direction will not heimpaired by the creeping of the rail in a reverse direction, but

which during the creeping of the rail in the reverse direction -will remain in such relation to the tie and rail that it will immediately prevent creeping when traffic is resumed in the normal direction, or after the rail has contracted.

A still further object of my invention is to provide a rail anchor which will resili ently grip a rail transversely of its base; so that any tendency of the gripping portion ofthe rail to creep toward an adjacent tic will'oscillatethe anchor about its fulcrum against the tie and cause the, anchor to rigidly grip the rail and prevent its movement toward the tie.

A still further object of my invention is to provide a rail anchor formed of a single piece of plate metal, such as heat-treated steel, which will under all conditions rigidly look a rail against creepingtoward an adjacent tie.

My invention will be more fully disclosed hereinafter with reference to the accompanying drawings, in which the same is illus trated as embodied in a convenient and practical form, and, in which,"

' D indicates the time in which the ties are embedded.

E designates my improved rail anchor whichis preferably made of a single piece of plate metal, such'for instance as heattreawd steel.

6 designates the lower portion of the anticreeper, which is preferably convex toward the adjacent tie, so that the tie will not be injured by the forcible engagement there- 5 with of the anti-creeper? Projecting upwardly from the tie-abutting portion 6 is a member F, which engages the under-surface may be received between them. The members G and Gr are formed by bending or twisting the portions of the metal on the opposite sides of the central member F into planes at right angles to the plane of the tie-abuttingportion a, so that the portions of the members'G and G which engagethe opposite sides; of the rail base extend 1n planes "arallel to the side edges of the rail to form flanges H and H which overlie the upper surfaces of the rail base adjacent the side edges thereof. The inner surfaces ofv the members G and Gflimmediately below $0 the flanges H and H are preferably substantially vertical, as indicated at h and h so as to engage the vertical edges b and b of the railbuse throughout the height of such'edges; The distance between the porti0ns= 7L and It", whentheanti-creeper is disengaged from the rail base, is slightly less' thanthe transverse width of the rail base,'-so-that .when theanti-creeper is engaged'avith the rail, the rail base will be 40 resillently gripped in a transverse plane.

The manner of a 7 )lvin and the 06cmtion of myrim-proved rail anti-creeper are' as follows: The device is placed beneath the'base of a rail adjacent .atie, with the flanges-H. and H" immediately beneath and .in engagement with the;opposite side edges of'the rail base. The device isthenvforced upwardly so that the .members G and G are sprung apart sufficiently to permit' the flanges H and H? to 'pass, upwardly above. theside-edges of the rail base. "Immedi-f ately upon the antircreeper being forced upwardly relatively to therail asutlicient dis-.

' tanc'e, the, flanges H and H?- spring in-' wardly as to overlie the upper surfaces of the rail base adjacent the. side' edges thereof and permit the. portions h. and hgaging-pneof the fiangcs Hf, and Htiyith the corresponding side of the rail bas e,

use. "he upper ends of the members G r 5 andG are bentdownwardlyand inwardly. with the upperv surfacesof the mix base. 90

Any tendency, therefore, of the rail to creep.

a a the estate h 't tt tettat' then tilting the anti-creeper soas tojforce the opposite flange around the adjacent side of the rail base. After the anti-creeper has been engaged with the rail buse it is-forc'ed i toward the adjacent tie until the transverse tie-abutting member 0 thereof bears against the v'eirtical surface of thetie, and until the upper edge of the central member F ti htly engages the undeisurface'of the fail ase, andthe lower, edges of the flanges H and 76 H? are drawn downwardly into gri'pping contact with the upper surfaces of the rail. base adjacent the side edges thereof, M Any tendency of therall to creep toward the tie imparts a correspondingtendency, to 80 rock the anti-creeper about the tie as a ful-, crum, through theengagement of the transverse member a with the vertical surfaces of the tie. Such tendency of the anti-creeper to rock causes the upper edge of the central 86 member; F .to mor'e tightly grip the under surfaces of the rail base, ,and the lower edges of the flanges Hvand H? to be forced down} wardly into tighter gripping enga ment toward the tie results in the anti-cree r be! ing more tightly clamped to the rai base,"

and hence more forcibly resisting the move ment ofthe rail toward the tie. The grip )ing engagement of the anchor with the rail base is increased by reusonof the inclination v of the central member I! away fro n'the tie, so that the plane of the upperqedge of such ;centralc memberwill be. at n angle to the plane of the under surfaces of the base; and hence the angular edge'of the central mem-i ber F is forcedyagainst. the under surfaces of the rail base.

The transverse resilient gripping of the, rail betweenith'e members (it and.

transverse gripping of the rail base insures the anchor being oscillated toward the tie,

brought into-tightly'gripping engagement with the rail basez In Fig. I I' have shown a modifiedform of my invention, in' which only one of the pair of members which grip the sides of the ,rail base is twisted or bent into a plane at right angle to the plane'of the tie-abutting portion, the other member of said pair extending in the same transverse plane as the tie-abutting member. In Fig. 4, G desighates the member which has been twisted so .ber of the pair which projects transverse of the rail base The member G is provided 4 with an upwardly projecting lug II at its upper end, which overlies the upper surface of the rail base. Asubstantially vertical portion his provided immediately below the lug H, which engages the adjacent vertical edge of the rail base. The operation of the modified form of my invention shown in Fig. 4 is similar to that above described in connection with the form of my device shown in Figs; 1, 2 and 3. I In applying the form of my invention shown in Fig. 4, to the rail, the member G is preferably first engaged with the railbase, and the device then oscillated so'thatthe flange H of the other member G will be forced aroundvthe adjacent side ofthe rail base so as to overlie the upper surface thereof.

If desired, thetie abutting member 6 may be provided with one or more holes 6 or e through which spikes K may be driven into the adjacent surface of'the tie in order that the rail anchor may at all times be retained against the tie in position to be rocked relatively-thereto by the creeping of the rail towardthe tie.

From the foregoihgldescription it will be observed that I have invented an improved rail anchor which is exceedingly simple in construction and easy of application, and which will at alltimes prevent the creeping of a rail in a given dir'e'ctiom and will not be rendered ineife ctiveto'prevent creeping of the rail in such'direction even though'the rail may temporarily creep in an opposite direction. ii i i.

\Vhile I havedescribed more or less in detail the. specific embodiment of my invention herein illustrated and described, it will engage a tie, a. pair of members projecting upwardly from said tie-engaging memberto extend around and transversely grip, the base of a rail, one member of saidpalr hav-.

ing its greatest dimension extendingjlongitudinally of the rail base, and a member projecting upwardly from said tie-engaging member intermediate of and disconnected from the members of said pair to engage the under surface of the rail base at a pointfarther from the engaged tie than the en-'; gagement of said pair of members with the rail base. j

2. A rail anchor comprising a member to engage a tie, a pair of members projecting upwardly from said tie-engaging member, to resiliently grip in a transverse direction the opposite sides of the base of a. rail and having inwardly projecting flanges overlying the rail base, the greatest dimension of one member of said pair extending longitudinally of the rail base, and a. member projecting upwardly in an-inclined direction from said tie-engaging member intermedi-. ate of the connections therewith of the members of said pair to engage the under surface of the rail base at a point farther from the engaged tie than the engagement of said diate of and spaced apart fromtheX-mem- 5 I bers of said pair to engage the under' sur-u face of the rail base.

4. A rail anchor comprising a fulcrum member to beamagainst a tie, a pairof spaced resilient members projecting upwardly from said fulcrum mer'nber'to trans- ,versely grip and extend over the opposite sides of the base of a ra-il,,the portions of said pair of members which engage the rail base projecting in planes parallel to the edges of the rail base, and a member projec'ting upwardly from said fulcrum member intermedia of the members of said pair and Fin an inclined direction away from the tie into engagement with the under surface of the rail base.

5. A rail anchor formed of a single piece of plate metal and comprising a pairv of transversely resilient members to engagethe opposite sides of a rail base, the plane of one member of said pair extending longitudinally with respect to the side. edges of the rail base, a tie-abutting member at the lower ends of said pair of members, and a-central member projectingupwardly in an.inclined direction from said tie-abutting member intermediate of. and disconnected from the members of said pair, 'With its I upperedge engaging, the under .surface'of the rail base at a point farther from thctie than the engagement of said pair of memberswith therail base.
